8.关于日期格式 |?g k%g
(wkeo{lx
日期格式设定 bNi\+=v<Ys
DataFormatString="{0:yyyy-MM-dd}" 40+~;20
ngE5$}UM
我觉得应该在itembound事件中 ?!KqDI
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ry0P\wY}

9.获取错误信息并到指定页面 z^bv)u
N"Q-xK
不要使用Response.Redirect,而应该使用Server.Transfer It&$R`k
mGb,oj7l
e.g g,*L P
// in global.asax @uApm~}
protected void Application_Error(Object sender, EventArgs e) { "{Lp'+wNw
if (Server.GetLastError() is HttpUnhandledException) qf#Ou
Server.Transfer("MyErrorPage.aspx"); pKMy:j
r Z%l?(
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Yv\>\?865
} Dn1aaN6
X|++K;rtfE
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 llN#4D9s
